Does anyone know if the MFK test checks the mileage of imported cars please?

I'm in the process of importing my UK car, and it's booked in the MFK the week after next. This week I went to Customs to get a 13.20 form for the car, and they decided I had to pay duty on it. To work out the duty, they asked how much I'd paid for the car and its mileage. At the time, I remembered it as about 27500Km, so to be safe I said 27000. They valued the car and I paid the duty.

However, I've just got back into the car for the first time since then, and found that the mileage is actually 23700Km...

I've heard that the different government bodies here share data a lot, so now I'm worried that if the MFK check against the info I gave to Customs, they'll think I was trying to reduce the duty on the car...

So, am I being paranoid, or do I need to do a lot of driving this week please?

You're being paranoid. Forget about it.

They are going to catch you and put you in prison, a heavy fine and the rest

Forget about it.. you will be alright.. no probs at all..

OK thanks guys, that's good to know

It's hard to tell where the data sharing line is here, for instance when I registered for the MFK test the woman in the MFK said they'd had a small problem with my insurance, seen as the insurance company had my name written down slightly differently to my B permit, and they didn't the Stammnummer customs had given to the car.
So I called my insurance company today to update these details, and found that the MFK woman had done it for me! It's slightly worrying to know that a complete stranger, even one acting in an offical capacity, can call up and change such basic details as my name on something so important...

Do you not like the flexibility? You miss the bureaucracy?

lol, oh I think CH has it's fair share of bureaucracy, seems to be one of those universal constants in the universe!

Seriously, it just concerns me from a data security point of view. We all know that you should protect certain basic personal details to guard against fraud, and if it's that easy for someone to not only access but change confidential data...

Data protection is taken very seriously in Switzerland. After all it is the home of the renowned (notorious?) banking secrecy.

The vehicle licensing authority has mandatory access to vehicle insurance details. So what confidentiality was infringed? The insurer rectified the error and resubmitted. So it was not "someone" who changed the data but the original issuer.

It's just the fact they were able to change details on my insurance. In the UK, the police and such can view insurance details, but never ever change them. Only the policy holder can do that.
I guess I'm just used to a system where access to these sorts of things is, in theory anyway, much more restricted...
